Fig. 1. Disease reaction of 558 accessions of Pisum sativum to Mycosphaerella pinodes, based on the mean result over 2 yr of detached-leaf (A) assays and field trials (B). Means for the detached-leaf assay (A) were based on a 0-to-4 scale, and for field trials (B) on a 0-to-9 scale.

Fig. 2. Blight severity in 558 accessions of Pisum sativum inoculated with Mycosphaerella pinodes in detached-leaf assays (A) and field trials (B) in 2003 and 2004. Severity was assessed 5 d post-inoculation in the leaf assays, and in mid-August in the field trials.
